The Watchtower (Observability)

A tower that watches every ship in the harbour without boarding one of them. By the end you’ll have built a small one from a single container and read three things off it.

Before you start. You need to know what a pod is: Kubernetes’s word for one running copy of your program, which it can kill and restart elsewhere without asking you. That’s the whole problem here: once nothing stays in one place, you can’t watch it by logging in and looking.
